Common bathroom remodel budget mistakes
- Forgetting what is behind the walls. Plumbing is the second-biggest job on the list, and water damage or old pipes are found only once the walls are open: about 1 in 3 homeowners in This Old House’s survey spent more than they expected for exactly those reasons. Keep money spare.
- Moving the toilet or the shower. Keeping the fixtures where they are keeps the plumbing cost down.
- Pricing materials, not labor. The ranges here include installation; a shop’s price for a vanity does not.
- One quote. Prices move a lot with where you live. Ask two or three contractors, and ask what each quote includes.
